phpmailer 发送图片

php对邮箱地址进行检测

function PageIsMail(array $email_arr){
    foreach($email_arr as $email) {
        //邮箱正则匹配（不能以-_.开头）
        if (!preg_match("/^[0-9A-Za-z][0-9A-Za-z-_.]*@([0-9a-z]+\.[a-z]{2,3}(\.[a-z]{2})?)$/i", $email)){
            echo "(method1)invalid email: $email<br />";
            continue;
        }
        //名称在4到16位之间
        if (strlen(explode("@",$email)[0])<4 or strlen(explode("@",$email)[0])>16 ){
            echo "(method2)invalid email: $email<br />";
            continue;
        }
        //域名是否存在（依赖网络，不建议使用）
        if(checkdnsrr(explode("@",$email)[1],"MX") === false) {
            echo "(methodof3)invalid email: $email<br />";
            continue;
        }
        echo "email: $email<br />";
    }
}

phpmailer 发送带图片的邮件

原理：

　　1、将html中的图片文件(本地直接添加，网络图片则需要下载)加载为邮件附件$mail->addEmbeddedImage(pic_path, 附件id)

　　2、将html中的图片代码替换成<img src="cid:添加附件时的id" />

直接上代码

// 发送邮件
function SendMail(){
    require_once("./class.phpmailer.php");
    $mail = new PHPMailer();
    //$mail->SMTPDebug = 3;
    $this->mail=$mail;
    $this->mail->isSMTP();
    $this->mail->CharSet = 'UTF-8';
    $this->mail->Host = 'smtp.exmail.qq.com';
    $this->mail->SMTPAuth = true;
    $mail->Username = 'xxx@xx.com';
    $mail->Password = 'pwd';
    $this->mail->SMTPSecure = 'ssl';
    $this->mail->Port = 465;
    $this->mail->From = 'xxx@xx.com';
    $this->mail->addAddress('yyy@yy.com','toName');
    $this->mail->isHTML(true);
    $this->mail->Subject = '中文主题测试';
    $hmtl = '<i>帅哥</i>：<b>你好</b>！！！<br><img src="./static/pic/xx.png" /><br><img src="./static/pic/xx.png" />';
    //带图处理，不带图不处理，图片格式如上（图片未加格式）
    $this->mail->Body = ProcessImg($hmtl);
    $this->mail->AltBody = strip_tags($hmtl);
    if(!$this->mail->send()) {
        echo 'Message could not be sent.';
        echo 'Mailer Error: ' . $this->mail->ErrorInfo;
    } else {
        echo 'Message has been sent';
    }
}

// 处理MailBody中的图片，将本地图片加入附件方可发送成功
function ProcessImg($html){
    $resutl = preg_match_all('@<img src=.+? />@', $html, $matches);
    if(!$resutl) return $html;
    $trans = array();
    foreach ($matches[0] as $key => $img) {
        $id = 'img' . $key;
        preg_match('/src="(.*?)"/', $html, $path);
        if ($path[1]){
            $this->mail->addEmbeddedImage($path[1], $id);
            $trans[$img] = '<img src="cid:' . $id . '" />';
        }
    }
    $html = strtr($html, $trans);
    return $html;
}
